HARROW.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed April 9,1906. Serial No. 310,756.

To all whmn it may concern:

Be it known that we, HALE V. ABBOTT and NATHAN W. ABBOTT, citizens ofthe United States, residing at Lawton, in the county of Van Buren andState of Michigan, have invented certain new and useful Improvements inHarrows, of which the following is a specification.

This invention relates to steering means for harrows.

The main object of this invention is to provide an improved guidingmeans for harrows and similar tools which may be effectively controlledby the operator, thereby adapting a harrow for use in orchards,vineyards, and the like.

It is also an object of our invention to provide a simple and effectivesteering means which can be attached to harrows alreadyin use or to anyharrow, although the harrow may be of a new design, whereby the harrowmay be effectively guided.

Further objects and objects relating to details of construction willdefinitely appear from the detailed description to follow.

lVe accomplish the objects of our invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and point ed out in the claims.

A structure embodying the features of our invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which I Figure 1 is a plan view of a structureembodying the features of our invention, the steering means being shownin one of its adjusted positions by dotted lines; and Fig. 2 is anenlarged detail vertical section taken on a line corresponding to line 22 of Fig. 1 looking in the direction of the little arrows at the ends ofthe section-lines, the steering-Wheel being shown in an elevatedposition by dotted lines.

In the drawings similar letters of reference refer to similar parts inboth views.

Referring to the drawings, the harrow may be of any design offloat-harrow. It is preferably made up of sections or wings A, securedtogether by hinges a. T o the rear cross-piece A of the frame of one ofthe sections we secure by suitable clips B the rearwardly and upwardlyprojecting arms B. To these arms we secure by horizontally-arrangedpivots c a suitable frame consisting of arms 0 and O, secured to a blockD by projecting arms D. A standard E is secured to this rectangularframe by the vertical pivot e. A steering-disk E, with sharp edge, isjournaled on a horizontal journal upon the lower end of the standard E.A steering-handle projects rearwardly from the standard E. This handleis adjustably secured to the standard E by a bolt f, which is arrangedin the slot 0 in the standard. A brace F is provided for the handle.This brace extends from the lower end of the standard up to the handleand is secured thereto by a bolt f, which is arranged through the slot fin the brace. By thus securing the handle it may be adjusted verticallyto bring the same to a proper height for the particular user. By thus arranging the parts we provide a harrow which may be steered close to thetrees or vines in an orchard or vineyard without danger of engaging thesame, as the harrow is held steadily in position by the steering-wheel.It is found in practice that in harrowing orchards and vineyards aharrow is likely when driven close to trees or vines or their bases tobe thrown into contact with the trees or vines, injuring the same inspite of the care of the operator. With our im rovements, as abovestated, the ground may be harrowed close to the trees or vines withoutliability of injuring the same.

A further advantage is that the ground or space between the trees orvines may be harrowed by working the harrow in and out While drivingalong the rows by means of the steering-Wheel. By placing thesteeringwheel at the inner rear corner of the frame, as illustrated anddescribed, it is brought into position to operate most efiectively anddoes not interfere with the usual operation of the harrow.

When not in use, the steering device can be folded over upon the harrow,so that the space required for storage is not materially increased onaccount of the steering attachments.

Our improved steering device is comparatively light and is very easy tomanipulate. It is very easy to manufacture and is readily attached toany harrow. WVe have illustrated and described the same in detail in theform preferred that it is capable of variation in structural detailswithout departing from our invention.

by us, although we are aware IIO Having thus described our invention,what we claim as new, and desire to secure by Letters Patent, is-

1. An attachment for a harrow consisting of the clip-pieces B arrangedto attach to one of the cross-bars of the harrow; a frame pivoted byhorizontal pivots to said clip-pieces; a standard arranged to swing on avertical pivot, carried by the said frame; a steering disk-like wheel onthe horizontal journal on said standard; and a steering-handle securedto said standard, coacting for the purpose specified.

2. An attachment for a harrow, consisting of a a vertical pivot carriedby the frame; a standard arranged to swing on said vertical pivot; adisk-like wheel on a horizontal journal on said standard; and arearwardly-extending steering-handle secured to said standard by which1t may be raised from the ground or thrown into the ground and pressureapplied thereto, or turned on its pivot, coacting for the purposespecified.

3. The combination of a harrow made up of sections hinged together; apair of upwardly and rearwardly projecting arms secured to the frame ofone of said sections; a rectangular frame secured to said arms byhorizontally-arranged pivots; a standard secured at the inner rearcorner of said frame,

by a vertical pivot; a disk-like wheel jourframe supported on ahorizontal pivot;

naled on said standard; and an upwardly and rearwardly projecting handlesecured to said standard, for the purpose specified.

4. The combination of a harrow made up of sections hinged together; apair of upwardly and rearwardly projecting arms secured to the frame ofone of said sections; a frame secured to said arms byhorizontallyarranged pivots; a standard secured to said frame, by avertical pivot; a disk-like wheel journaled on said standard; and ahandle for said standard, for the purpose specified.

5. The combination with a float-harrow, of a frame connected to saidharrow by a horizontally-arranged pivot; a vertical pivot; a standardjournaled on said pivot and secured to said frame thereby; a disk-likeWheel journaled on said standard; and a rearwardlyextendingsteering-handle for said standard by which it may be raised from theground or thrown into the ground and pressure applied thereto, or turnedon its pivot, for the purpose specified.

In witness whereof we our hands and seals in witnesses.
